_Dear Authorized,_
_I have a question related to seedlink connection._
_My connection code is below:_
from obspy.clients.seedlink.easyseedlink import \*
def handle\_data(trace):
print(trace.stats.station)
print(trace.stats.endtime)
client = create\_client(‘[remote.org:18000](http://remote.org:18000)’, handle\_data)
station = ‘ABC’
net = ‘CD’
client.select\_stream(net, station, ‘EL?’)
client.run()
_My goal is to connect to the seedlink server and do station query. I’m linking with the code above. But I can’t get a return from handle\_data._
_If the station is coming to the seedlink server, I want to do the same query for another station after reading the end time and receiving this information._
_How can do it? can you help me?_
_Best regards,_
_Recai._

Hi Recai,
did you have a look at this example?
> **[obspy.clients.seedlink.easyseedlink.EasySeedLinkClient — ObsPy 1.4.2...](https://docs.obspy.org/packages/autogen/obspy.clients.seedlink.easyseedlink.EasySeedLinkClient.html)**
You would have to parse that xml string yourself, though, but that should be simple.
There's also this page for the easyseedlink client:
> **[obspy.clients.seedlink.easyseedlink.EasySeedLinkClient — ObsPy 1.4.2...](https://docs.obspy.org/packages/autogen/obspy.clients.seedlink.easyseedlink.EasySeedLinkClient.html)**
If you're able to use the current development version of obspy, a convenience routine implemented for the basic client, but thats not in the stable release yet:
> **[obspy.clients.seedlink.basic\_client.Client.get\_info — ObsPy...](https://docs.obspy.org/master/packages/autogen/obspy.clients.seedlink.basic_client.Client.get_info.html)**
The code parsing the xml response is here, in case you need it:

>
> Adds a method to seedlink client to be able to fetc…h a list of network/stations for which waveform streams are provided.
>
> \### Why was it initiated? Any relevant Issues?
>
> This can help in applications to resolve wildcards in stations/networks, e.g. when using \`seedlink-plotter\` with \`"GR\_\*:HHZ"\` as seedlink string because the realtime version of the seedlink client can not handle wildcards in network/station.

Dear Tobias,
Thank you very much for answering my question.
Yes, I’ve tried everything you’ve suggested. I didn’t get any results, so I asked for help. I use opspy version 1.1.1. It has not “obspy.clients.seedlink.basic\_client.Client.get\_info” on this version.
My goal is to check the stations come to seedlink server one by one. I writed code for this. it is below.
from obspy.clients.seedlink.easyseedlink import \*
import pymysql
def handle\_data(trace):
networkCode = trace.stats.network
channel = trace.stats.channel
station = trace.stats.station
print(trace.stats.station)
print(trace.stats.channel)
print(trace.stats.endtime)
```python
```
